Very good performance and load testing capabilities
There are some compatibility issues with the load standpoint test. When we use the solution instead of Microsoft Edge, more scripting is required. The reports for structure point or test management could be more compatible with other tools. For example, when I create an application I sometimes cannot generate a report.

Cloud-based testing has simplified remote mobile validation and provides flexible device coverage
I was not impressed with how detailed their analytics and logs are from LambdaTest. The solution we were testing is being used because many of us are working from home. It was easy to implement because with a real phone, we have to bring a real phone to each person. Since three years ago, many employees have been working from home, so we were trying to find a solution for this challenge. We had no need to exploit the information for the analytics generated in the background. The purpose was simply to make it easy for our employees to access a phone. The downsides I noticed include that the pricing was very good, but the visual quality of the image sometimes suffers. The contrast on a real iPhone provides better contrast than with the cloud solution. The only aspect that was less favorable than on a real phone was the contrast of the color.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Before using Telerik Test Studio, I was a manual tester, so it was my first automation tool, yet I felt very comfortable using it. I've used the record and play feature, and Telerik Test Studio was easy to use. The tool was easy to understand, even for a first-time user like me."
"The most valuable aspects of the solution are the font, size, and interface."
"The way it identifies elements is good."
"Has a very smooth process for launching and closing the application after execution."
"The performance and load testing are very good."
"Our test execution time was reduced to 16 mins from five hours when executed in parallel on multiple VMs. This has been extremely helpful!"
"LambdaTest supports multiple platforms like iOS across different devices and enables real-time testing."
"Automation and mobile testing have improved our efficiency."
"The slow nature of a cloud platform was compensated with parallel testing, and now we are able to finish our testing job faster than it was before COVID."
"We use the solution for automation testing and monitoring."
"LambdaTest is easy to use, and the documentation provides all the needed information."
"The UI is pretty clean and easy to navigate, and we were able to figure it out very quickly."
"The most valuable features are that it's essentially on-demand, and you only focus on getting the code that needs to be executed without having to worry about the OS, hardware, etc."
 

Cons

"Its UI is not very user-friendly and could be improved. For new users, it isn't easy."
"It can be improved by including a feature that allows multiple file types to be selected simultaneously."
"I observed that the Excel and Word validation was quite challenging, which is an area for improvement in the tool. I also experienced minor difficulties with Telerik Test Studio, particularly in fetching elements in some scenarios when using C# for coding."
"There are some compatibility issues with the load standpoint test."
"The charts need to be more detailed and customizable."
"Improvements on a platform need to happen on a timely basis...There should be some new features coming up or some performance improvisation over a period of time."
"Responsive testing UI is a bit cluttered, whereas the LT browser is much better to use."
"If possible to simulate the finger pinch, it would make it more realistic."
"I've also had some issues with the speed of certain API calls and the rendering of data. For example, when I'm onboarding data, the process can be slow."
"I would like to see all of the features available in the freemium plan so that I can test them."
"Mobile application testing would be helpful for us."
"LambdaTest needs to improve its speed and memory because it takes a long time to load."
"Load flow compared to other stacks needs improvement."
 

Pricing and Cost Advice

"LambdaTest is paid per execution."
"LambdaTest is priced well, which is why we migrated to it."
"The pricing for LambdaTest is affordable, and one of the reasons we implemented it."
"The pricing could be made cheaper."
